GB2RS News
Sunday the 9th of February 2025
The news headlines:
- A new RSGB web page focuses on emerging technology
- An upcoming talk at Bletchley Park Museum aims to widen awareness of the radio spectrum and radio transmission
- Remember to share your British Science Week ideas
The RSGB has launched a new web page on how emerging technology can be used in amateur radio. Technologies such as artificial intelligence and 3D printing offer the opportunity to broaden the definition of amateur radio. They can also increase appeal and attract a more diverse audience. For existing radio amateurs, they offer the opportunity for progression through learning new skills. You’ll also find links to two RSGB Convention presentations, including the newly released talk on 3D printing by Tom Wardill, 2E0JJI. Go to rsgb.org/emerging-technology to learn more. The Society will be adding more technologies to the web page in the coming months and would love to hear from you if you are involved in amateur radio in any of these areas.

On Saturday the 29th of March, the RSGB National Radio Centre Coordinator, Martyn Baker, G0GMB, together with Andy Webster, G7UHN from the Radio Communications Foundation, will be delivering a talk in the Fellowship Auditorium at the Bletchley Park Museum. The presentation will introduce people to the radio spectrum and how to get to grips with the fundamentals of radio transmission. The session is being delivered as part of the RSGB’s ongoing strategy to promote amateur radio to wider audiences. The Society is pleased to announce that RSGB members who would like to attend the talk can benefit from a 10% discount, reducing the price to £14.40. To find out more about this talk, go to the ‘What’s on’ section on the Bletchley Park website via bletchleypark.org.uk If you'd like to visit the Bletchley Park museum after the talk, don’t forget that RSGB members can gain free entry by downloading a voucher from the RSGB website via rsgb.org/bpvoucher
British Science Week is less than a month away and the RSGB would love you to use your interest, expertise and enthusiasm for amateur radio to get people involved. The annual event takes place between the 7th and 16th of March and celebrates science, technology, engineering and maths. Perhaps you love going portable and could take a local rambler group on an activation with you, or maybe you’re a member of ‘Men in Sheds’ and could deliver a soldering demonstration for them. The Society wants to make amateur radio accessible and inclusive for everyone. All ideas are welcome, both big and small. Whatever you are planning, send your ideas to the RSGB British Science Week Coordinator, Ian Neal, M0KEO via bsw@rsgb.org.uk The RSGB will continue to share resources and ideas for how to get involved via rsgb.org/bsw
A competition has been launched for RSGB Regions 6 and 7 in Wales that will take place throughout March. The aim is to encourage both individual RSGB members, as well as Affiliated Clubs in Wales, to build their own resonant 21MHz antenna and make as many QSOs as possible on the 21MHz band during the month. There are four categories to enter, with certificates issued to the top three stations in each of the categories. A club trophy is also available. To view the full competition rules and to access the submission form, go to tinyurl.com/walescomp
Don’t forget that Girlguiding groups will be taking part in World Thinking Day on the Air activities over the weekends of the 15th and 22nd of February. The event aims to encourage Girlguiding members to make friendships with those in other units, using amateur radio as the means of communication. A list of stations that have provided the RSGB with details of their callsign can be found by going to rsgb.org/thinking-day If you’d like to be added to this list, please email comms@rsgb.org.uk

Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO on Wednesday the 5th of February 2025
Last week went pretty much as predicted. The solar wind from a large coronal hole impacted the Earth on Saturday the 1st of February, pushing the Kp index to four. The hole was so large that the geomagnetic disturbance lasted until the early evening on Sunday.
Once the solar wind speed had dropped, things got back to normal and the Kp index has been in the range of 1 to 2 ever since.
The event appeared to have had little effect on HF propagation, with maximum usable frequencies over a 3000km path remaining above 28MHz during the daylight hours. So it looks like we dodged a bullet.
At the time of writing, we have had 21 M-class flares in three days.
A solar flare measuring M8.8 was detected around active region 3981, peaking at 0358UTC on the 3rd of February. This was the strongest flare yet from this region in terms of peak X-Ray flux. However, the flare itself was impulsive and was not the source of a coronal mass ejection.
Over the next week, NOAA predicts that the solar flux index could fall slightly to be in the 180 to 200 range. Make the most of the good propagation as we may be entering a period of unsettled geomagnetic conditions again from the 10th to the 17th of February. NOAA predicts that the Kp index could rise to a maximum of 5 on the 13th but is likely to be in the range of 3 to 5 over the seven days.
Part of this may be down to another coronal hole which became Earth-facing on the 6th of February. There is also a good chance that we could get an X-class eruptive flare from active regions 3981 or 3978, which could result in a coronal mass ejection.
We recommend you keep an eye on solarham.com for daily updates.
And now the VHF and up propagation news from G3YLA and G4BAO
High pressure during the second half of last week brought some useful tropo conditions. As this week, ending today the 9th comes to a close there are some wintry showers along North Sea coasts, which may produce some snow and rain scatter. However, this may be weakened by the nearby high pressure.
By the end of this week, ending today the 9th, there will be a change of weather pattern as the high, having now migrated to Scandinavia, leaves room for Atlantic weather systems to encroach from the west during the coming week. This could bring rain scatter possibilities to the western side of the country. These should be more useful than the eastern coast ones at the end of last week since the rain will probably be heavier and the fronts slow-moving.
This time of year is something of a desert for Sporadic-E propagation although look out for lesser events as a result of jet streams. You can track these on the Propquest website.
Keep a look out for auroras during the week beginning tomorrow, the 10th. The likelihood of M-class flares is around 85%, while the chance of X-class flares is approximately 20%. So keep an eye on the Kp index for any potential solar events that could cause auroras.
Next week, there are no major meteor showers. The next significant meteor shower, the Lyrids, will become active in April. Keep checking the pre-dawn period for random meteors.
Moon declination reached a maximum yesterday, Saturday the 8th. Path losses are still low but will increase throughout the coming week. This means that this weekend, ending today the 9th, should produce good activity for EME, especially on the GHz bands with long Moon windows and high peak Moon elevation.
144MHz sky noise is moderate this weekend, ending today the 9th, but falls to low for the rest of the coming week.
And that’s all from the propagation team this week.
